Dry/Plasma Etch GaN Process Development Engineer (SM1) - Sherman, TX, United States
Originally posted 10 September 2026 by the employer.
About the role
This role is responsible for developing, optimizing, and transferring advanced plasma etch processes supporting GaN semiconductor technologies. The engineer will work closely with integration, equipment, metrology, and manufacturing teams.
What you'll do
- Develop and optimize plasma etch processes for advanced semiconductor devices.
- Design and execute experiments (DOE) to improve critical process metrics including etch rate, selectivity, critical dimension (CD) control, profile control, defectivity, and uniformity.
- Partner with equipment engineering teams to improve tool capability, productivity, and reliability.
- Analyze complex process datasets using statistical methods and data analytics tools.
- Present technical findings and recommendations to management and key stakeholders.
What you'll need
- 5+ years of semiconductor plasma/dry etch process development experience.
- Bachelors in an engineering, science, or related STEM discipline.
- Strong foundation in statistical process control, engineering change control, and process release strategies.
- Experience with DOE methodologies and statistical analysis.
- Familiarity with metrology techniques including SEM, CD-SEM, ellipsometry, and defect inspection tools.
Nice to have
- Experience in Gallium Nitride (GaN) and/or similar wide-bandgap III-V nitrides processes and technology development.
- Proficiency with Python, Claude, or other AI models or tools.
- Experience with process development and transfer on etch platforms (LAM, AMAT, TEL).
